regarding the postulates of the kinetic theory, in each book or page that are different, that is, in more and less sites... even in some cases with contradictory redactions, and hence my doubt... in one place I read a postulate: - There are no intermolecular forces except during the collision between molecules and yet in another place this appears as a postulate: Collisions between two molecules do not exert unattractive or repulsive forces... this is not contradictory...? are there or are there not intramolecular forces during the collision, according to the postulates of kinetic theory.????
